Museuminsel (Museum Island) is located on Spree Island in the Mitte section of Berlin, and officially consists of the Altes Museum, the Neues Museum, the Alte Nationalgalerie, the Bode-Museum and the Pergamonmuseum, although there are several other museums (including the Humboldt Forum, German Historical Museum, James Simon Gallery), and historic landmarks (Berlin Cathedral, Ehemaliges Staatsratsgebäude der DDR, Ribbeck-Haus, Hanns Eisler Academy of Music - New Marstall), not to mention a large library branch, restaurants and other businesses that inhabit the rest of the island.
Without going into too much detail, here's the main focus of each of the 5 museums:
1) Altes Museum - the first museum built on the island, displaying selected classical western sculpture, jewelry, and household objects of Etruscan, Greek, Roman origin.
2) Neues Museum - collections include pre-western history, Egyptian, Greek, Roman works, and a famous bust of Nefertiti.
3) Alte Nationalgalerie - the building is modeled after a Greek temple, housing paintings and sculptures from the artistic Ages of Classicism, Romanticism, Biedermeier*, Impressionism and early Modernism.
4) Bode-Museum - featuring Byzantine art, a numismatic (aka relating to coins, currency, and medals--I had to google this) collection, and European sculptures from the Middle Ages to 19th century.
5) Pergamonmuseum - one of the foremost museums worldwide for Greek and Roman art. Famous for the Pergamon Altar, a sculptural frieze depicting a battle between gods and giants, and the Museum of Islamic Art. Currently closed for renovations until 2027.
Tickets can be purchased for each museum individually or as a single day pass (24 hours) for €24, either online in advance or in person. For those museum fans out there, a Berlin Museum Pass for €32 exists which allows admission over 3 days to 30 museums around Berlin. Separately, admission is free the first Sunday of each month throughout state-affiliated museums in Berlin, including those on Museuminsel, though be forewarned the lines can be long. Especially at the Alte Nationalgalerie I waited over an hour to enter, the other museums had no more than a 10-15 min wait. They do not allow you to purchase timed tickets in advance for free Sundays.
If you want to go thru all 5 museums, trying to fit them into one day is tight, I'd suggest trying to fit in 3ish. Overall highly recommend checking out at least a few and hopefully all of them at some point if you have more time to explore!
*period of Central European art and and culture between 1815-48 transitioning between Neo-Classicism and Romanticism, often associated with stagnation in evolution of artistic style due to aligning art production to the prevailing popular tastes of the rising of middle class.
